TWYER ATTACHMENT FOR BLACKSMITHS FCRGES.

SPECIFICATION formingpart of Letters Patent No. 759,768, dated May 10, 1904.

Application filed January 16, 1904.

T0 61/ whom it n'uw concern.-

Be it known that I, EDWARD E. TABER, residing at Pratt, in the county of Pratt and State of Kansas, have invented a new and Improved Twyer Attachment for Blacksmiths Forges, of which the following is a specification.

My invention seeks to provide an improved attachment for blacksmiths fire-box, adapted to be connected with the blower or bellows pipe and to readily control the size of the (ire in such manner that when set to provide for a desired size of fire the said fire will not spread, as is usually incident in the use of the lire-controlling appliances for fire-pots now generally employed.

Another object of my invention is to provide an attachment of the character stated that can be connected with the ordinary types of blacksmiths fire-box and bellows, which is of an economical and simple construction, and can be readily applied for use by any blacksmith.

In its generic nature my invention comprehends a hollow body having a series of gratelike apertures in its upper face adapted to be placed under and in contact with the regular fire-pot grate and means for regulating the number of the apertures desired to be in open communication with the grate at all sides of the central air-conveying member, which is adapted to be coupled up with the bellows or blowers.

My invention in its more complete makeup comprises a cylindrical body, a T-joint connected therewith and discharging into the same centrally and through the under side thereof, the said cylinder having its upper side provided with a series of grate-like airoutlets extended at opposite sides of the point where the T- joint communicates with the said cylinder, and a pair of independently-operating plunger cut-offs slidably mounted within the cylinder and arr. nged to force the ashes that accumulate within the cylinder toward the pendent portion of the T member.

In its more subordinate features my invention consists in certain details of construction and peculiar combination of parts, all of which will be hereinafter fully described, and spe- $e1'ial No. 189,354. (No model.)

cifically pointed out in the appended claim; reference being had to the accompanying drawings, in which Figure 1 is a vertical longitudinal section of my fire-pot attachment, showing the same applied in position under the fire-pot grate. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 1, and Fig. 3 is a horizontal section thereof on the line 3 3 of Fig. 1.

In its practical construction my invention comprises a cylinder 1 of suitable length and diameter, preferably thi rty 'inches long and of four inches inside diameter. At the top side midway its length the said cylinder has a series of transversely-extemled apertures 1, that project, in the practical arrangement of my invention, about nine inches each way from the center of the cylinder, and the said apertures 1 are tapering and widest at the bottom to allow for a free discharge of the ashes that pass through the fire-pot grate G into the cylinder. Centrally the cylinder 1 has a large opening (0, preferably three inches in diameter and located in the bottom thereof, and with the said opening communicates the upper end 2 of the vertical portion of the hollow T member 2, in the lower end of the pendent portion of which operates a cut-off valve 2 for a purpose presently explained.

The upper end of the T member 2 is concaved to snugly it around the cylinder 1, and the said upper end has a flange 2 for conveniently bolting the said T member to the cylinder 1, as shown.

The lower extension 2 of the T member 2 has a flange 2 for attaching it to the bellows or blowers, (indicated by B.)

4 designates a hollow plunger that snugly fits and is slidable within one end of the cylinder 1, and 5 designates a similar plunger that fits and slides in the other end of the cylinder 1, and both plungers 1 and 5 have their closed ends projected toward the opening a and facing each other, and the said plungers are of a length sufiicient when drawn inward the plunger or cut-off is manipulated by an actuating-rod 7, made fast to the head f) of the member 5, and the said rod 7 passes through an aperture 4 in the head 4 of the opposing plunger and extends backwith the rod 6 to a point convenient for handling.

From the foregoing description, taken in connection with the appended claim, it is believed the complete operation and construction of my invention will be readily understood by those skilled in the art to which it appertains.

The plunger cut-olfs 4 and 5, it should be stated, are fitted in the cylinder 1 practically air-tight, and hence danger of air leaking in at the ends of the cylinder is practically avoided, and no draft will pass up through the grate except through the openings in the cylinder that are uncovered between the heads of the opposing plungers into the cut-offs 4c and 5.

The plunger cut-offs can be readily set to produce anarrow space for the air-current to provide for a narrow fire, or they can be separated to provide an air-space the full length of the apertured portion of the cylinder 1.

The plunger cut-offs, while primarily used for controlling the size of the fire, are also utilized for forcing any ashes that may drop into the cylinder at each side of the opening a through the said opening into the pendent leg of the T-joint, which forms an ash-receiver and from which the ashes can be readily exhausted by opening the gate in the lower end thereof.

The several parts constituting my invention are so combined that they can be easily assembled, and when placed in an operative position they provide a compact and stable means for controlling the size of the fire in the lire-box as conditions may make desirable.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a twyer attachment for fire-pots of the character described, the combination with an open-ended cylinder having a series of transversely-disposed outlets in one side and an oppositely-disposed inlet at the other side and disposed midway the ends of the cylinder, a cylindrical member 2 open at both ends and connected at one end to the first-mentioned cylinder at the inlet-apertures thereto, a gate 2 for closing the other end of the second cylindrical member 2, said second cylindrical member 2 having an angled tubular extension thereto, serving as an inlet to the member 2, a pair of hollow cylindrical cut-ofis 4 and 5 each having one end open and their other ends closed, said closed ends being disposed adjacent each other, an operating-rod 6 connected with the cut-off a and passing therethrough, an operating-rod 7 connected with the cut-ofi 5 and passing through an aperture in the closed end of the cut-off 4 and through the said cut-ofi 4, said cut-off being so arranged as to be independently adjustable, for the purposes specified.
